Coleotechnites gibsonella

The common juniper leafminer (Coleotechnites gibsonella) is a moth of the Gelechiidae family. It is found in the north-eastern parts of the United States.

The wingspan is about 11 mm. The forewings are white, shaded with yellowish at the apex and crossed by three oblique dark brown bands. The hindwings are yellowish-gray. There is one generation per year.

The larvae feed on Juniperus communis. Young caterpillars mine or hollow the needles of their host at the ends of shoots and ties the dead needles together with silk. In fall, it lines the center of the bundle with silk to make a chamber where it spends the winter. In spring, the caterpillar moves to new terminal growth, again binding hollowed needles together with silk.
